CA 2359281

Various circuit configurations for use in switch assembly used in a surgical hand piece system are provided. The circuit configuration provide a number of functions such as permitting the presence and direction of conductivity to be detected. The circuit configurations also provide a means for detecting and measuring the degree of influence of debris which is located between the conductive members of the handpiece. In addition, the circuit configurations also provide a means for identifying the type of switch end cap which is attached to the handpiece. The handpiece body and the switch mechanism are electrically connected to one another in such a manner that permits the switch end cap to be freely rotated about the handpiece body and reduces the number of conductive members needed to communicate the status of each switch.

L'invention concerne diverses configurations de circuit à utiliser dans un interrupteur utilisé dans un système chirurgical de pièce à main. La configuration de circuit offre un certain nombre de fonctions comme le fait de permettre de déceler la présence et la direction de la conductivité. Les configurations de circuit offrent également un moyen de déceler et de mesurer le degré d'influence des débris se trouvant entre les éléments conducteurs de la pièce à main. De plus, les configurations de circuit offrent également un moyen de nommer le type de bouchon du commutateur qui est attaché à la pièce à main. Le corps de la pièce à main et le mécanisme à commutateurs sont connectés électriquement l'un à l'autre d'une façon qui permet au bouchon du commutateur de tourner librement autour du corps de la pièce à main et qui réduit le nombre d'éléments conducteurs nécessaire pour communiquer l'état de chaque commutateur.
